Come on guys, They said its going to have A bigger campaign, Mulitplayer (13-16 maps), Strike Force, A FULL LENGTH ZOMBIES CAMPAIGN, and Zombies (being fully dedicated to it) (1-4 maps or more if they have 2 disc) and the xbox can only hold 8 GB and all of that wont fit in one CD..............

Yes it cn all fit ruiz. They haven't upgraded the engine at all. It's going to be revised, plus the fact that as seen with MW3 they now know how to free up as much space as possible per map by not having the maps all physically loaded, but having the textures marked, already downloaded, and just loaded into the maps as opposed to loaded AS the maps.

they no longer made it under the campaign enginge. They have switched the engine to the multiplayer engine. Just a heads-up. Apparently there's a difference. I don't know how or what the differense is but it was stated by Lamia.

Most map packs are pretty big I am not so sure you are right about this. 4 or 5 maps = over a gig of space so figure at least 12 maps but more from what I have heard and you have taken up half your disc space.

That's only in infinity ward's case, who use the single player campaign as Spec Ops missions... when you download a map which is something between 60-200 mb it might use very few elements from the disk but you're downloading into ur hard drive completely new pixels that aren't on the disk

Why? Just so you can buy Zombies separately and forget about the MP/campaign. Crafty ******. You buy the game as a package besides it will cost Activision more to make two disks instead of 1 and that's just one of the problems.
